L'accroche
Media problems are rarely isolated. A hero image without dimensions can shift layout; an image without alt text can block accessibility and weaken visual understanding.
Comment ça marche
FixWeb records rendered image elements, alt attributes, dimensions, loading mode, fetch priority, and rendered size.
Le rayon d'impact
Missing alt text affects screen-reader users; missing dimensions increase CLS risk; lazy-loaded hero images can delay the page's primary visual.

The rendered DOM snapshot inventories visible images and flags missing alt attributes, weak alt text, absent dimensions, and lazy loading on probable hero images.
Défenses blindées
Use an image component or CMS pipeline that requires alt text, emits width/height, generates responsive sources, and treats the first major visual as priority content.
